Car started to run real rough so I thought to check the knock setting on the SAFCII and it read 20 at idle and 86 at 1320 rpms. I Also when I rev the car it is sluggish to get up there and hesitates. Think its a bad sensor?

 

Um.... probably.

 

are you just guessing or you think it really is? Anyways its easy to get to so im going to change it tomarrow night.

 

No im not guessing. It'll be a bad knock sensor. If you've never replaced it and your car has done more than 100,000 km's its a high possibility.

 

its got 79k on but still going to give it a shot.
